Body parts, body coverings and behaviors
- Most marine animals descended from land and possess qualities that evolved slowly over time. From habitat to adaptations, land and sea dwelling animals have both similar and different characteristics. The most differences lie in body parts, body coverings and behaviors, such as how the animal moves.

Nov 5, 2018 · For an explanation of the predominance of strategies based on the release of eggs or larvae to the “care” of the physical environment, we need to consider the differences between the marine and terrestrial habitats in terms of their oceanic and atmospheric environments and look more closely at the dynamics as well as the statics.

When comparing terrestrial and marine lineages, one observes distinct evolutionary divergences. Land mammals like hippopotamuses are surprisingly the closest living relatives to cetaceans, indicating a shared lineage before fully adopting an aquatic lifestyle.
Apr 16, 2015 · Separated in time by more than 50 million years, modern dolphins and extinct ichthyosaurs descended from different terrestrial species but still developed a similar fish-like body. Dolphin, NOAA...
Jul 12, 2017 · In particular: flowering plants, fungi, and insects, so many damn insects. By one estimate, there are five times as many terrestrial species as marine species today.
Several species that originated on terrestrial landscapes ventured back into the watery depths of oceans and seas, giving rise to unique marine animals. This evolutionary path reversed the ancient migration that once brought primitive sea-dwelling organisms onto land to colonize and thrive.
The physical differences between marine and terrestrial systems clearly impact the way in which organisms interact with each other and their environment.
Oct 1, 2012 · As discussed above, marine and terrestrial systems clearly differ in diversity, so any general theory of coexistence ought to be able to explain patterns for both species-rich terrestrial and phylum-rich marine systems, and to predict the conditions under which exceptions occur.
